dtft程序图源代码，本科生毕业设计程序( DTMF, by itself, creates a new DTMF or raises the existing )

切比且夫线阵幅度加权方向图计算,画出二位方向图,图示中标示出增益,副瓣电平等(Ratio and the linear amplitude weighted directional graph computation, draw two direction map, marked gain the diagram, the sidelobe level etc. )

This model shows the implementation of a QPSK transmitter and receiver. The receiver addresses practical issues in wireless communications, e.g. carrier frequency and phase offset, timing offset and frame synchronization. The receiver demodulates the received symbols and outputs a simple message to the MATLAB command line.
